Hana Williams died in the backyard of the family's home in May 2011. Prosecutors said she was starved, beaten and forced outside as punishment.

Defense lawyers argued that questionable parenting practices don't necessarily amount to a crime. Lawyers for both husband and wife said an appeal is likely.

Hana is believed to have been 13, but no documentation of her birth in Ethiopia was available. The trial was postponed several times and her body was exhumed in January. Tests on her teeth and bones gave varying estimates and experts were unable to agree on her age.

Her age was significant because the homicide by abuse charge applies only if the victim was younger than 16.
